No writer should be on twitter or any other social media outlet either. All writers should be free to decide which social media outlets (if any) work for them. For some of you that will be twitter, for others it won’t. And that’s absolutely fine.

If you’re enthusiastic about twitter, it will work for you. If you lack enthusiasm, it will show and could lose you readers.

What’s not fine is publicly criticising other writers for their choices. There is no one-size-fits-all answer to marketing and reader engagement.
